FIRE-EXTINGL JISHING APPARATUS.-

SPECIFICATION forming part of Letters Patent No. 285,146, datedSeptember 18, 1883.

Application filed April 21, 1883. (No model.)

. in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is a front elevation of my improvement shown as applied to abuilding. Fig. 2 is a front elevation of a part of the same shown inanother position. Fig. 3 is a sectional plan view of a part of the sametaken through the broken line x 00 x m, Fig. 1.

The object of this invention is to facilitate the extinguishing of firesin buildings. A represents anordinary pump, which is worked by anordinary engine, B. The en'- gine B receives steam through a pipe, 0,from a boiler, which boiler is not shown in the drawings, as there isnothing new in its construction. The steam-pipe O is provided with avalve, D, for controlling the admission of steam to the engine, and witha branch pipe, E, the ends of which are connected with the said pipe (3,upon the opposite sides of the valve D, so that the steam can beadmitted to the engine B independently of the valve D. The branch pipe Eis also provided with a valve, F.

G is the inlet or suction pipe of the pump,

which is designed to be. connected with a well,

a water-main, or other water-supply.

H is the discharge-pipe of the pu1np,-with which is connected a pipe, I,leading to a tank upon the roof or in the upper part of the building.With the discharge-pipe H is also connected a pipe, J, leading throughthe various stories of the building. The pipes I J are provided,respectively, with valves K L, so that the water can be directed througheither pipe, as may be desired. The pipe J, upon each story of thebuilding, is provided with a discharge-cocl ,,M, and a hose, N,connected with the said cock M, as shown in Fig. 1.

0 is a bar extending up through the various stories of the building, andwhich slides vertically in guides 1?, attached to the wall of thebuilding or other suitable support.

the said lever.

Upon the bar 0, on each story of the building, is formed or to it isattached a section of rack-teeth, Q, into which mesh the teeth of asmall gear-wheel, R, journaled to a support attached to the wall of thebuilding. One of the journals of the gear-wheel R projects, and isprovided with a tongue to fit into a grooved hole in the end of a lever,S, so that the bar 0 Q can be raised and lowered by operating The tongueupon the journal of the gear-wheel R and the groove in the lever preventthe possibility of placing the said lever upon the said journal in awrong position, and prevent the said lever from turning upon the saidjournal. The levers S, when not in use, are hung upon nails or othersupports attached to the wall of the building. To each lever S isattached the end of a cord or chain, T, which passes over guide-pulleysU, pivoted to supports attached to the ceiling of the room. The otherend of each cord or chain T is at tached to a lever, V, connected withthe valvestem of the cook M. With this construction, when one of thelevers S is used to operate the gear-wheel R and raise the bar 0, themovement of the said lever will operate the cord or chain T and thelever V to open the cock M upon that floor and allow water to pass fromthe pipe J into the hose N.

To the outer end of each lever V is attached a weight, \V, of sufficientgravity to close the cock M when the cord or chainT is slackened andprevent any more water from entering the hose N. r

To .the lower part of the bar 0 is hinged the upper end of a shortbar,X, the lower end of which is hinged tothe adjacent ends of two shortbars, Y Z. The outer end of the bar Y is hinged to the wall of thebuilding, and the outer end of the bar Z is hinged to the end of a baror frame, a, which is connected by two or more bolts, 1), with a bar, 0.The bar chas short slots formed in it to receive the bolts 1), and to itare attached pairs of pins d, or other suitable keepers, to receive theends of the levers e f, the other ends of which are pivoted to supportsattached to the valves K L, which levers are also pivoted to the stemsof the said valves. The otherend of the baror frame a projects, and isforked to engage with the lever g, which is pivoted to the stem of thevalve F and to a support attached to the said valve, and

operates the said lever to close the said valve F. The bar or frame a isconnected with the lever g by a small chain, h, which is made of such alength as to be slack when the bar or frame a is in position to closethe said valve. With this construction, when the rack-bar O is raised bythe movement of a lever, S, in opening a valve, M, to admit water into ahose, N, it draws the bars ac outward,which closes the valve K in thewater-pipe I, leading to the tank, opens the valve L in the water-pipeJ, leading through the building, and then opens the valve F to admitsteam to the engine, "the slackness of the chain h allowing the valvesin the waterpipes to be adjusted before the valve in the stean1pipe isopened. \Vhen the raclebar O is lowered into place, the movement of thebars a b opens the valve K, closes the valve L, and closes the valve F.

The operation is as follows: The valves L F being opened and the valve Kclosed by the peration of he bar 0 through the in orvc i g mechanism,the steam passes through pipe E, setting the engine 13 and pump A in inotion and forcing the water through the open valve L and p n J to henozzle N; To mak tho cv c opcra v ivli n 'a' il annot be fu nished tothe engine the tank at the top of the building is provide S0 that theremaybe an vatcd up'p y o vo er tan ly on hand asc of fi c- Thi a er flowso t e ozzles through the pipe J. The bars ac being gid y onne te o ll lc K L Rthc valve K ann c p c to dm t Wa e th ough the pipe I to supplythe tank without shutting off the snpply of steam to the engine andstopping ho P1 1 1 Th p p 0 is t rc r pr vided to admitsteam to the pumpat the time when the valve K is opened, so that the tank may be suppliedwith water at the will of the operator.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of the rack-bar O, hav ing toothedsections, pinions, and chain-connected levers, with mechanism leading tothe valves of hose-pipe, tank-pipe, distributingpipe, and steaminletpipe, as and for the purpose specified.

2. In a fire-extinguishin g apparatus, the combination, with thehosepipe valves M, of the bar having racksections Q, the gearwheels R,the separable levers S, the chains and pulleys T U, and the weightedlevers V V, substantially as herein shown and described, whereby thehose-pipe valve up on any desired floor can be readily opened, as setforth.

3.
